Definitions

  • This invention relates to a truck mounted forklift. More specifically, this invention relates to a truck mounted forklift with an alternative lifting assembly.
  • Truck mounted forklifts are a highly specialised type of lightweight forklift truck that can be mounted on the rear of a truck or trailer for transport to and from customer's premises. Once at the customer's premises, the truck mounted forklift can be dismounted from the rear of the truck and used to load and unload goods from the truck or trailer before being remounted onto the rear of the truck or trailer for transport to the next customer's premises.
  • the truck mounted forklifts must be lightweight as any increase in truck mounted forklift weight will correspond to a decrease in available haulage capacity of the truck or trailer about which it is mounted. Furthermore, the truck mounted forklifts must be compact in a fore and aft sense as the amount by which the truck mounted forklift may protrude from the rear of the carrying vehicle (commonly referred to as "overhang") is restricted by law in many jurisdictions. Furthermore, the greater the overhang, the greater the forces applied to the mounting. Increased forces necessitate reinforcement of these components which typically leads to increased weight which as described before is highly undesirable.
  • An example of one such truck mounted forklift is that disclosed in the Applicant's own granted European Patent No. EP1711428 .
  • the present invention is concerned solely with this type of specialised lightweight forklift truck and is to be considered in light of the limitations of truck mounted forklifts.
  • the present invention is in no way intended to relate to other types of forklift trucks such as the commonplace heavyweight counterbalanced forklift trucks that are not so restricted and do not require the same design considerations.
  • moving mast and static mast implementations typically comprise a pantograph linkage or other mechanism to increase the reach of the forks carried on the mast. While each of these configurations has advantages, each also has a distinct problem with loading and unloading the top far side of a container or trailer. Due to the height of the pantograph arrangement, moving masts with pantograph sections cannot reach under the top of containers or trailers. Static mast machines can only reach the far side of a trailer if they can drive the front wheels under the truck or trailer which is not always possible.
  • a truck mounted forklift for mounting on the rear of a vehicle according to claim 1.
  • the forklift truck will not be inhibited by the limitations of the known lifting assemblies.
  • the forklift truck will be able to reach top far side loads without coming into contact with the roof of the trailer; will not have to drive its front wheels under the trailer and will not interfere with lower near side loads when attempting to engage top far side loads.
  • This is seen as a particularly useful configuration of lifting assembly.
  • the lifting assembly will not interfere with the rear steering set-up at any stage during its movement.
  • a lower collapsed height is achieved with the addition of a third link. It is envisaged that the range of motion of the forks will be improved by incorporating a third linkage.
  • a truck mounted forklift in which one of the link cylinders, a main lift cylinder, is connected to the chassis at one of its ends and connected to the first link at the other of its ends.
  • a truck mounted forklift in which the tilt cylinder is connected at one of its ends to the fork carriage and at the other of its ends to the second link.
  • each pair of adjacent connected links is further coupled together by one of the link cylinders.
  • a truck mounted forklift in which there is provided a control system operable to synchronise the operation of the tilt and link cylinders.
  • a control system operable to synchronise the operation of the tilt and link cylinders. This allows the driver to securely move loads in a variety of directions including horizontal or vertical directions by synchronizing the operation of the link cylinders.
  • the control system operable to synchronise the operation of the tilt and link cylinders will provide a smoother motion of the lifting assembly and will self-level the load by controlling the tilt cylinder, thereby speeding up the loading and unloading of goods.
  • a truck mounted forklift whereby the linkage is configured to not extend rearwards beyond the rear wheel of the chassis when fully retracted. This results in the truck mounted forklift having no more overhang than previous models.
  • a truck mounted forklift in which the linkage is configured to prevent the second link from pivoting rearwardly beyond a substantially vertical orientation with respect to the ground. This is particularly advantageous as this configuration will ensure that the lifting assembly will not interfere with a load mounted on the fork carriage.
  • a truck mounted forklift whereby the lifting assembly further comprises a carriage slidably mountable on the chassis, the carriage being slidable towards and away from the rear crossbar and means to move the carriage back and forth along the chassis, and in which the proximal end of the first link is mounted on the carriage.
  • This implementation extends the possible reach of the forks.
  • a truck mounted forklift in which the first link is cranked intermediate its ends. It is envisaged that the second link may be cranked intermediate its ends. It is further envisaged that the third link may be cranked intermediate it's ends.
  • a truck mounted forklift in which the third link is shorter in length than the first link. In one embodiment of the invention, the third link is shorter in length than the second link.
  • a truck mounted forklift in which the lifting assembly is mounted centrally across the truck mounted forklift substantially in line with the longitudinal axis of the truck mounted forklift.
  • Figures 1 (i) to 1 (ix) inclusive there are shown views of truck mounted forklifts with known lifting assemblies.
  • Figures 1 (i) to 1 (iii) illustrate a truck mounted forklift 1 with a movable mast 3 having a pantograph linkage 5.
  • Figures 1 (iv) to 1 (vi) illustrate a truck mounted forklift 1 with a static mast 7 having a pantograph linkage 5.
  • Figures 1 (vii) to 1 (ix) illustrate a truck mounted forklift with a telescopic boom 9.
  • the truck mounted forklift with a movable mast is illustrated engaging a load 11 in a variety of positions on a carrying vehicle 13.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the bottom far side position of the carrying vehicle.
  • the movable mast 3 is positioned forwards on the forklift 1 and the pantograph linkage 5 is fully extended.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the top near side position of the carrying vehicle. It can be seen that there are no impediments to the lifting assembly engaging loads in these positions.
  • the truck mounted forklift with a static mast is illustrated engaging a load 11 in a variety of positions on a carrying vehicle 13.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the bottom far side position of the carrying vehicle.
  • the front wheels 17 of the truck mounted forklift 1 are positioned under the carrying vehicle 13.
  • the static mast 7 is in position on the forklift 1 and the pantograph linkage 5 is fully extended.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the top far side position of the carrying vehicle 13.
  • the truck mounted forklift with a telescopic boom is illustrated engaging a load 11 in a variety of positions on a carrying vehicle 13.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the bottom far side position of the carrying vehicle.
  • the telescopic boom 9 is positioned forwards on the forklift 1 and is fully extended.
  • the truck mounted forklift 1 is shown engaging a load 11 located in the top near side position of the carrying vehicle. It can be seen that there are no impediments to the lifting assembly engaging the load 11 in these positions.
  • the truck mounted forklift is shown attempting to engage a load in the top far side position on the carrying vehicle.
  • the lifting assembly 100 comprises a linkage, the linkage comprising a first link 101, a second link 103, a third link 105, a fork carriage 107 and a pair of forks 109.
  • the linkage comprises a plurality of link cylinders 111, 113 and 115 for actuating the links 101, 103 and 105 and a tilt cylinder 117 for actuating the fork carriage 107.
  • Link cylinder 111 is also referred to as a main lift cylinder.
  • the first link 101 is connected at its proximal end to a chassis (not shown) at a pivot joint A.
  • the second link 103 is connected at its distal end to a fork carriage 107 at a pivot joint D.
  • the first link is connected at its distal end to one end of the third link 105 by a pivot joint B and the second link 103 is connected at its proximal end to the other end of the third link 105 by a pivot joint C.
  • the first link 101 is actuated by the main lift cylinder/link cylinder 111 which is connected at one end to the chassis (not shown) by a pivot joint E and at the other end to the body of the first link 101 by a pivot joint F.
  • the second link 103 is actuated by link cylinder 113 which is connected at one end to the body of the third link cylinder 105 by a pivot joint I and at the other end to the body of the second link cylinder 103 by a pivot joint J.
  • the third link 105 is actuated by link cylinder 115, which is connected at one end to the body of the first link 101 by a pivot joint G and at the other end to the body of the third link by a pivot joint H.
  • the fork carriage 107 is actuated by the tilt cylinder 117 which is connected at one end to the body of the second link 103 by a pivot joint K and at the other end to the fork carriage by a pivot joint L.
  • the truck mounted forklift 20 has a similar construction (with the exception of the lifting assembly) to the truck mounted forklift described in the Applicant's own granted European Patent No. EP1711428 , the entire disclosure of which and in particular the disclosure relating to the general physical construction of the forklift truck is incorporated herein by way of reference.
  • the truck mounted forklift 20 comprises a U-shaped chassis having a pair of forwardly projecting side bars bridged by a rear crossbar, a wheel 17 adjacent the forwardmost end of each of the side bars and a rear wheel 21 mounted on the rear cross bar.
  • a driver's station mounted to one side of the chassis, a motive power unit mounted on the other side of the chassis, and a lifting assembly (100, 200) mounted on the chassis.
  • FIG. 3 there is shown a truck mounted forklift 20 picking up a load 11 from the top far side position of the carrying vehicle 13. It can be seen that the lifting assembly 100 is not obstructed by the load in the bottom near side position or by the roof 15 of the container and that the front wheels 17 do not need to be positioned under the carrying vehicle 13.
  • FIG. 4 there is shown a truck mounted forklift 20 picking up a load 11 from the top near side of the carrying vehicle 13. It can be seen that the lifting assembly 100 is not obstructed by the container.
  • FIG. 5 there is shown a truck mounted forklift 20 picking up a load 11 from the bottom far side of the carrying vehicle 13. It can be seen that the front wheels 17 do not need to be positioned under the carrying vehicle 13.
  • FIG. 6 there is shown a truck mounted forklift 20 picking up a load 11 from the bottom near side of the carrying vehicle 13.
  • FIG. 7 there is shown a truck mounted forklift 20 with the lifting assembly 100 in a retracted position having picked up a load 11 from the bottom of the carrying vehicle 13. It can be seen that no part of the lifting assembly 100 extends substantially behind a rear wheel 21 of the truck mounted forklift. This ensures the load overhang and overall truck or trailer length is kept to a minimum.
  • FIG. 8 there is shown a truck mounted forklift 20 with lifting assembly 100 in a raised, retracted position.
  • FIG. 9 there is shown a truck mounted forklift 20 with lifting assembly 100 in a lowered, retracted position having picked up the load 11 from the carrying vehicle 13. This is a stable position for driving. It can be seen that the transition from the retracted positions shown in Figure 7 and 8 to the lowered and retracted position shown in Figure 9 does not require that the linkage 100 extends substantially beyond the rear wheel 21 and does not destabilise the truck mounted forklift 20. It can also be seen that the height of the linkage in the collapsed position does not add to the overall height of the machine.
  • FIG 10 there is shown a truck mounted forklift 20 with lifting assembly 100 in an extra lowered and retracted position having picked up the load 11 from the carrying vehicle 13.
  • This extra lowered position is enabled by the u-shaped chassis.
  • This is a particularly stable position for driving, picking up or placing heavy loads. It can be seen that the transition from the retracted positions shown in Figure 7 and 8 to the lowered and retracted position shown in Figure 10 does not require that the linkage 100 extends substantially beyond the rear wheel 21 and does not destabilise the truck mounted forklift 20.
  • FIG. 11 there is shown a truck mounted forklift 20 with lifting assembly 100 in a slightly retracted position having picked up the load 11 from the highest point in its reach.
  • FIG. 12 there is shown a truck mounted forklift 20 with lifting assembly 100 in position to pick up the load 11 from the highest point in its reach.
  • FIG. 13 there is shown a truck mounted forklift 20 with lifting assembly 100 in position to pick up or put down the load 11 at ground level.
  • FIG 14 there is shown the lifting assembly 100 in a retracted position. It can be seen that the second link 103 of the lifting assembly 100 does not touch the load 11.
  • FIG. 15 there is shown a truck mounted forklift 20 with lifting assembly 100 fully retracted for transport.
  • the truck mounted forklift is mounted on the back of the carrying vehicle 13. It can be seen that the lifting assembly 100 does not extend behind the rear wheel 21 unless the rear wheel 21 is rotated to a stowed or turning configuration.
  • FIG 16 there is shown a truck mounted forklift 20 with lifting assembly 100 in a retracted configuration.
  • the driver's station has been omitted for clarity. It can be seen that the first link 101 of the lifting assembly 100 does not interfere with the rear steering set-up.
  • the lifting assembly 200 comprises a linkage, the linkage comprising a first link 201, a second link 203, a fork carriage 207 and a pair of forks (not shown). There is further provided a plurality of link cylinders (not shown) for actuating the links 201, 203 and a tilt cylinder (not shown) for actuating the fork carriage 207.
  • the first link 201 is connected at its proximal end to a chassis 208 at a pivot joint M.
  • the second link 203 is connected at its distal end to the fork carriage 207 at a pivot joint O.
  • the first link is connected at its distal end to the proximal end of the second link 203 by a pivot joint N.
  • the first link 201 and the second link, 203 are cranked intermediate their ends.
  • a linkage comprising one or two straight links is also envisaged.
  • the truck mounted forklift 30 is shown picking up a load 11 from the top far side position of the carrying vehicle 13. It can be seen that the lifting assembly 200 is not obstructed by the load in the bottom near side position or by the roof 15 of the container and that the front wheels 17 do not need to be positioned under the carrying vehicle 13.
  • FIG. 18 there is shown the truck mounted forklift 30 picking up a load 11 from the top near side of the carrying vehicle 13. It can be seen that the lifting assembly 200 is not obstructed by the roof 15 of the container.
  • FIG 19 there is shown the truck mounted forklift 30 picking up a load 11 from the bottom far side of the carrying vehicle 13. It can be seen that the front wheels 17 do not need to be positioned under the carrying vehicle 13.
  • FIG. 20 there is shown a truck mounted forklift 30 picking up a load 11 from the bottom near side of the carrying vehicle 13.
  • FIG. 21 there is shown the truck mounted forklift 30 picking up a load 11 from the ground forward of the front wheels.
  • FIG. 22 there is shown the truck mounted forklift 30 in a retracted position after picking up a load 11 from the bottom of the carrying vehicle. In this position the linkage 200 temporarily extends beyond the rear wheel 21.
  • FIG. 23 there is shown the truck mounted forklift 30 after picking up a load 11 from the top of the carrying vehicle. In this position the linkage 200 extends beyond the rear wheel 21.
  • FIG 24 there is shown the truck mounted forklift 30 in position for picking up a load 11 from the top near side of a carrying vehicle (not shown).
  • FIG. 25 there is shown the truck mounted forklift 30 with its forks in a lowered position for picking up a load substantially rearward of the front wheels.
  • FIG. 26 there is shown the truck mounted forklift 30 with the lifting assembly 200 in a slightly retracted position after picking up load 11 from the top of the carrying vehicle. In this position the lifting assembly 200 does not extend beyond the rear wheel 21.
  • FIG. 27 there is shown the truck mounted forklift 30 mounted on the rear of the carrying vehicle 13. It can be seen that with this configuration, the linkage 200 extends behind the rear wheel 21 of the truck mounted forklift.
  • the linkage comprises three links connected together. However, it will be understood that more than three links could be provided.
  • the linkage in each of the positions of the lifting assembly described above, can move horizontally or vertically from one position to another.
  • a control system which enables "tip control” in which all the cylinders work together to provide purely vertical or horizontal control of the forks for the driver.
  • the linkage may also tilt the fork carriage through the required forwards and backwards tilt in all positions. This will ensure ease of pick up and placement as well as security of transport.
  • one or more single acting rams may be used, or, alternatively, a double-acting ram may be used for each of the link cylinders 111, 113 and 115 and on the tilt cylinder 117.
